REFLECTOR SHIELD" FOR HEADLIGHTS.

This invention relates to head lights for vehicles and has for its object means for eliminating the glaring rays or for deflecting the rays away from the eyes of the driver of an approaching vehicle without diminishing the amount of driving light thrown on the road.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference had to the accompanying drawings in which like characters represent corresponding parts in all the views.

Figure 1 is a vertical sectional view of a headlight embodying our invention.

Figure 2 is a front elevation thereof.

This head light comprises generally a body orcase,'a concave reflector mounted in the case and carrying a lamp socket at its focal axis, a lamp. or other source of light mounted in the socket and light directing or deflecting means arranged in front of the source of light including deflectors arranged to shut oil the light rays from a person in front of the lamp, as the driver of an approaching vehicle, as the distance between such person or driver and the lamp decreases but without cutting down or modifying the amount of light projected from the source of light or reflected by the reflector.

1 designates the lamp case, it having an annular bearing face 2 at its front end.

3 is the concave reflector, 4 the lamp socket and 5 the source of light or la-i'np mounted on the socket 4. The reflector is suitably secured in position and as shown is provided with the usual annular flange 6 lapping the bearing face 2.

7 designates a glass or lens having its margin 8 opposed to the bearing face 2, and S) is a clamping ring for holding the glass or lens in position by clamping it toward the bearing face 2 and in so doing holding or clamping the reflector flange 6 and also the annular flange of the shield to be'presently described.

This shield comprises laterally extending deflectors 10 arranged horizontally in a lateral direction but inclining upwardly and rearwardly in radial directions toward the center 11 of the source of light, or a horizontal transverse line containing said center, these inclined reflectors being arranged one above the other below the horizontal plane of the focal axis of the head light or the reflector 3. The shield also 111- cludes deflectors 12 arranged one above the other in theuppcr half of the head light case or reflector, these deflectors also extending horizontally in a lateral direction and also horizontally in ,a rearward direction. That is they are parallel to the horizontal plane of the focal axis of the reflector 3. The shield also includes means as one or more deflectors 13 and 1% arranged in the upper right hand quadrant of the head light (look toward the light from the front) in front of and slightly above and to the right hand side of the axial light of the reflector 3. These deflectors 13 and 14 being of different inclination as seen in Figure 1 and of the outline or form hereinafter described.

Preferably the shield also includes horizontal and vertical vanes 15 and 16, which intersect in the focal axis of the reflector and hence divide the shield into quadrants. The deflectors 11v and 12 and the vanes 15 and 16 are supported by and secured to a flat ring 17, which fits into the front portion of the reflector 3 and this ring 17 is formed with an annular flange 18 interposed between the annular flange 6 on the reflector and a filler or washer 19 between the marginal flange of the glass or the lens and said flange 18.

' The deflector 13 inclines downwardly from the vane 16 to the horizontal vane 15 and lies in a plane forming the hypotenuse of a right isosceles triangle. The vane 14 is located to the outward of the vane 13 and at a less inclination out of the vertical plane. The front edge of the vane 13 is as shown in Figure 2 in the form of a point 20. That is the front edge is composed of two converg ing side edges of equal lengths, which meet in a point or apex. The rear edge of this deflector 13 is square and in the vertical plane of the rear edge of the vane 16.

The deflector 14 is in the form of an irregular quadrangular as shown. its front edge inclining from the upper edge of the deflector l4: rearwardly to the rear edge of the vane 15. The rear portion of this deflector 14: is formed with upper and lower converging edges, which meet in a point at one side of the lamp 5. These deflectors 13 and 1 1 are interposed between the vane 15 and the first deflector 12 directly above that vane 15.

By our light shield the various vanes and deflectors shut off the light rays from an approaching driver, the shutting-off effect increasing as the driver approaches, but the amount of driving light projected by the head light is not affected in so far as the driver of the vehicle provided with the light is concerned. Also the deflectors 18 and 14 facilitate the cutting off of laterally thrown rays, from the eyes of the driver of an approaching car when the driver is quite close to the ear provided with the head light.

lV hat we claim is:

1. In a headlight, a shield arranged in the headlight in front of the source of light and including a deflector arranged in the angle formed by horizontal and vertical planes intersecting in the axis of the headlight and inclined downwardly and laterally toward the horizontal plane, and a second inclined deflector arranged to the outward of the former deflector and arranged at a different inclined angle from the former deflector, the former deflector having its front edge in the form of a triangle and the second deflector being in the form of a quadrangular figure substantially as shown with its front edge inclining downwardly and rearwardly.

2. In a headlight, a light shield comprising vanes arranged respectively in horizontal and vertical planes and intersecting in the axis of the headlight, inclined deflectors arranged horizontally in a lateral direction one above the other below the horizontal vane, the deflectors extending rearward in planes extending in radlal dlrectlons relatively to the source of light and additional deflectors arranged in horizontal planes above the horizontal vane and deflectors inclining downwardly and laterally to the horizontal vane above and at one side of the, axis of the headlight.

3. In a headlight, a reflector, a lamp arranged with its source of li ht near the aXiS of the reflector and deflector located in the angle formed by the horizontal and vertical planes intersecting in the axis of the headlight, the deflector being arranged in front of the lamp at one side of the axis and inclinding downwardly and laterally, said deflector also'extending forwardly and rearwardly in a general direction parallel to the axis of the reflector and terminating in front of the lamp. r

4. In a headlight, a reflector, a lamp located with its source of light near the axis of the reflector and a deflector located in the angle formed by the horizontal and vertical planes intersecting in the axis of the headlight, the deflector being arranged in front of the lamp at one side of and above the axis and inclining downwardly and laterally, said deflector also extending forwardly and rearwardly in a general direction parallel to the axis of the reflector and terminating short of the lamp.

In testimony whereof, we have hereunto signed our names, at Rome, in the county of Oneida and State of New York, this 28th day of September, 1926.
